SPECIFICATION forming part of Letters Patent No. 228,866, dated June 15, 1880.

I Application filed January 7, 1880.

To all whom it may concern:

Be it known that I, SAMUEL M. OAWKER, of Denver, in the county of Arapahoe and State of Colorado, have invented a new and useful Improvement in Fluid-Measures 5 and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to fluid-measures of the class wherein the fluid, after being admitted into a chamber from a reservoir, is drawn out by a siphon-tube, and wherein the amount of liquid to be drawn is regulated by the position of the arm forming one leg of the siphon.

In an application now on file in the Patent Office I described aform of fluid-measure wherein the valve regulating the admission of liquid to the measuring-chamber was controlled by a cook or faucet operated independent of the measuring device and the liquid was drawn out through an adjustable arm, forming, in connection with the dischargepipe, a siphon for that purpose, the opening of the faucet to draw off the water closing the valve regulating its admission to the measure.

My present invention is designed as an improvement upon the form above described; audit consists, mainly, in controlling the valves for both the admission and discharge of fluid by regulating the position of the siphon arm; further, in the arrangement of both valves in one chamber, and also in the general construction of the operative parts, as fully hereinafter described and specifically claimed.

In the drawings hereunto attached, and forming part of this specification, Figure l is a front view; Fig. 2, a section on the line a: .r, and Fig. 3 a section on the line y y.

A represents a vessel or ineasure,which may be of any desired shape and material, but is preferably of metal, and of suflicientcapacity to contain the largest quantity of liquid to be bored out, as shown at c, for connection with a discharge-pipe, D, by which the liquid is drawn off by means of a faucet placed outside the vessel.

The main portion of the valveseat B is hollow its entire length, and one side of it is chambered, as shown at E. This chambered space extends from the opening 0, with which it is connected, around one side of the valveseat, nearly to the opening into the supplypipe.

F is a hollow conical valve, which fits closely within the part a, and is adapted to turn freely therein and to be tightened by the nut 00 on the outside. Upon the inner end of this valve is secured a hollow arm, Gr, having an open bent end, and which turns with the valve. The valve is provided with an opening, 0, on one side for the passage of liquid, which is adapted to register with the admission and discharge openings of the chamber, in the manner hereinafter described.

Upon the outer end of the valve F, which is squared to receive it, is an indicatingfinger, 01, adapted to travel around a gage-plate, which is marked for pints, quarts, and gallons, and with other terms to signify that the device is open or closed.

In the top of the case is a valve-chamber containing an ordinary float-valve, and having a hollow tube in which the valve-stem works, and an opening for indicating the height of the float, and consequently shows when the case is full and ready to be discharged.

The operation of this device is as follows, supposing the vessel to be empty: The indexfinger is placed in the position indicated by Fig. l, and liquid allowed to flow into the supplypipe. The position of the valve F at this time is such that its opening registers with the bore of the hollow angular portion 1) of the valve-chamber connecting with the supplypipe, the opening into the discharge-pipe being, of course, closed by the valve. The liquid thus admitted into the valve passes into the hollow arm, and thence into the vessel A, which it fills. The index-finger is then moved to the point marked Closed on the gageplate, putting the valve-opening out of register with both the admission and discharge pipes, and preventing any flow whatever. Supposing, now, that the vessel is full, and it is desired to withdraw,, say, one quart from it, the index linger is placed at the proper point on the gage, lowering the arm G, when the liquid will flow in the arm by its own weight, and pass through the hollow valve, the opening in which now admits it to the chamber E, communicating with the discharge-pipe,where it is controlled by the cock or faucet. If, however, a larger quantity of liquid is to be drawn, so that the arm G would be brought below the horizontal, such arm-would form the short leg of a siphon, the discharge-pipe forming the other leg, and the liquid could be continuously drawn off, as usual where siphons are employed. In this manner all the liquid could be Withdrawn; after which the arm would be raised by turning back the finger, and commu- 1. A fluid-measure consisting of a measuring-chamber, a supply-pipe for connecting the same with the reservoir, a pipe connected with the faucet or dischargepipe, and forming therewith the longer leg ofa siphon, and an adjustable shorter arm of said siphon, whereby the regulated amount of liquid may be drawn from the measure, in combination with a valve operated by the adjustable arm to connect the interior of the chamber withthe supply-pipe or with the discharge-pipe, as set forth.

2. In a fluid-measure, the combination,with a hollow valve-seat having inlet and discharge openings, of an adjustable arm whose shaft forms a valve by which the admission and dis charge of fluid is controlled, as set forth.

3. The combination of the adjustable arm, its shaft forming a valve, the chamber E, and the discharge-pipe, as set forth.

4. In a fluid-measure, the combination of a measuringchamber, an inletpipe, a hollow arm forming, in connection with the discharge-pipe, a siphon, an adjustable valve and a valve-seat having a chamber communicating with the said discharge pipe, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I
